<P>PROBLEM TO BE SOLVED: To provide a Pb-free solder alloy for a high temperature, mainly consisting of Zn, having a melting point of about 300-400°C, having excellent wettability and reliability, and particularly having excellent workability and stress relaxation properties. <P>SOLUTION: This Pb-free solder alloy having an elongation percentage of 50% or above and tensile strength of 70 MPa or above contains 1.0-15.0 mass%, preferably 2.0-9.0 mass% of Al, and contains at least one of Ge, Cu, Ag, Ni, and P as the need arises, and the residue consists of Zn except an inevitably contained element. <P>COPYRIGHT: (C)2013,JPO&INPIT |
